Allergies and asthma, are they connected?

Spring is beautiful time of the year, but it's also a key time of the year for seasonal allergies. As plants release pollen, millions of people with hay fever start to sniffle and sneeze.

General practitioner Dr Michael Sorani speaks to us about allergies, springtime and its connections with asthma.
